I think you have to define a macro that expands to use `first-order->higher-order' around the arguments that should be allowed as procedures. For example, if you want a primitive `P', then define `P' as (define-syntax-rule (P e ...) (real-P (first-order->higher-order e) ...)) and implement the function as `real-P'. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
